JBL continually engages in research related to product improvement. Some materials, production methods and design refinements are introduced into existing products without notice as a routine expression of that philosophy. For this reason, any current JBL product may differ in some respect from its published description, but will always equal or exceed the original design specifications unless otherwise stated.

3 VT4888DP-DA Midsize Powered Three-Way High Directivity Line Array Element, Integrated Audio System JBL DrivePack enclosures are equipped with a modular input bay that accepts either DPDA, DPIP, DPAN or DPCN input modules. Speaker-dependent processing such as crossover filtering and component equalization, time alignment and protection are not user-configurable. Options are available for connectivity, audio signal path and control functionality. DPDA (HiQnet Network Input Module with AES Digital Audio) The DPDA module adds AES/EBU digital audio input capability with analog audio backup, BSS Omnidrive HD digital signal processing and LevelMax multi-stage limiting. Its 100 Mb Ethernet networking (with daisy-chain capability), allows for Remote Control and Monitoring via HiQnet System Architect software. A rotary mechanical encoder allows for array identification and box positioning. Available monitoring functions include: audio input type, AES lock, input signal level, clip and gain reduction; ready / temp status; individual channel load status, signal level, clip and gain reduction; event logging and user alert messaging. Available remote control functions include: input type (analog or AES), input connector (XLR or Ethercon), input level, input polarity and mute; input compressor attack/release, ratio and makeup gain; individual channel gain and mute. Twenty, type-selectable input filters (10 System and 10 Guest filters) are available for system equalization along with user-adjustable input delay of up to 2 seconds and sub filter access (user-adjustable low pass filter for subwoofer systems; high pass filter for full-range systems). Signal generator functions (sine wave, swept tone, pink or white noise) are available to facilitate system testing and up to fifty presets can be stored internally. In addition, Master Control Panels and Master Monitor Panels allow for convenient grouping of control and monitoring functions for multiple DPDA equipped DrivePack enclosures, providing a powerful control/monitoring interface for large format line array or subwoofer systems. See JBL DPDA specification sheet for more information on DPDA input modules. DPDA INPUT MODULE BLOCK DIAGRAM AES/Analog AES/Analog AES/Ethernet AES/Ethernet DPIP (Optional non-networked dbx Input Module with basic functionality) The standard DPIP input module features analog audio inputs and sophisticated onboard digital signal processing technology. Precision bandpass filtering, limiting, time alignment, component equalization and automatic self-test functions ensure optimized performance. Rear panel controls include a 32-position detented rotary attenuator calibrated in 0.5 db steps, providing a 16 db range of control. The Enable Subwoofer Filter button is a momentary-contact switch that enables or disables an 80 Hz filter. For subwoofer systems, the low-pass frequency is set to 80 Hz when selected or 100 Hz when deselected. For full-range systems, the high-pass frequency is raised to 80 Hz when the Enable Subwoofer Filter button is selected.

The Vertical Beamwidth results range from a single box up to an 8-box array with 10 splay angles between adjacent array elements. All measurements provided herewith are derived from data gathered with a calibrated measurement microphone centered onaxis of the box or array, with polar data points taken symmetrically around the measurement axis. All polars were taken as groundplane measurements at a distance of 10 meters, with data gathered on 5-degree intervals from using the MLSSA measurement system.

8 VT4888DP-DA Midsize Powered Three-Way High Directivity Line Array Element, Integrated Audio System VERTEC DP System Arrays The VT4888DP-DA is an Articulating Line Array element designed for use in vertically-oriented, multi-box systems. A nominal horizontal coverage pattern of 90 is maintained, while setting the individual box angles allows the creation of arrays with varying vertical coverage angles. Vertical coverage of an array is a function of the number of boxes used and the splay angles chosen. VT4888DP-DA enclosures can be suspended from VT4888- AF or VT4888-SF array frames. Due to the use of JBL s patented S.A.F.E. suspension hardware system, rigid arrays can be constructed that can be tilted either upwards or downwards at radical angles. Front hinge bars are tightly coupled while rear hinge bars are used to set angles from zero to ten degrees for adjacent enclosures. No gaps appear on the array s front baffle due to trapezoidal box shape. No straps are required on the rear of the array. VT4888-AF (Array Frame) This array suspension frame is crafted of 6061 heat-treated aluminum and includes 11 (eleven) shackle attachment holes, set on 4" centers. Each hole has an I.D. (inner diameter) of 1" (25.4 mm) and is fitted with bronze bushings for long life. Fitted with SAE Grade 8 bolts, 7075 Grade aluminum receiver blocks and steel quick release pins with stainless steel restraining lanyards. The VT4888-AF can also be used to ground stack up to 6 enclosures. Also used with VT4882DP-DA subwoofers. Weight: 38 kg (83 lb). VT4888-SF (Short Frame) This array suspension frame is crafted in similar fashion to the VT4888-AF. The VT4888-SF is primarily intended for use with smaller clusters or distributed satellite arrays. Optional anchor for use on bottom of large arrays. Can be used to ground stack up to 4 enclosures. Also used with VT4882DP-DA subwoofers. Weight: 19 kg (42 lb). VT4888DP-ACC The VT4888DP-ACC includes items necessary for the proper transport and protection of one VT4888DP-DA. The accessory kit includes: (1) VT4888DP-DOLLY & (1) VT4888DP- COVER with rigid foam blocks and protective metal plates. The JBL DrivePack DP-3 with DPDA input module attaches to the back panel of a standard VT4888, creating the model VT4888DP- DA. Robust Crown amplification and onboard BSS digital signal processing are combined to create a compact, powerful, integrated audio system. Important Note: The VT4888DP-ACC is sold as a separate item. One kit should be ordered with each VT4888DP-DA or VT4888DP to ensure safe and reliable transport of each system in portable use. JBL Professional 8500 Balboa Boulevard, P.O.
